Title: Improvements in or relating to cask washing machines
IPC: B08B9/08
Filed: 1921-01-10
Abstract: 177,285. Hopkins, E. C. Jan. 10, 1921. Cleansing casks.-Relates to a machine for cleansing casks internally and externally. A cask h to be treated is first placed bung-hole downwards on a chock g situated at the lefthand end of the machine. From the chock it is lifted and deposited in turn on the nozzles of three devices i, j,. k, adapted to inject through the bung-hole hot or cold water, steam, and hotwater respectively, the weight of the cask operating the valves of the injecting-devices, which valves close automatically on the cask being removed. The lifting and depositing of the cask is effected by means of a link-carrier device b to which a combined rising and falling and reciprocating motion is given by counterweighted mushroom levers c operated by worm-and-wheel gearing from the shaft f. After leaving the last ejecting-device, the link-motion deposits the cask on arms l, the last washing (of hot water) being retained within it. The arms are lifted and permit the cask to roll on to a rumbling-device A where the rotation swills the inside of the cask thoroughly, the exterior being at the same time scrubbed, liquid being squirted on it if desired This operation concluded, radial arms throw the cask on to a device B, where it is rotated on driven rollers and idle rollers o until a spring-controlled pin finds and enters the bunghole ; the longitudinal centralization of the cask is effected by means of discs n urged inwardly by counterweighted levers. A second link carrier device b<1> now picks up the cask and passes it to a second set of injecting-devices p, q, r similar to the ones already referred to, whence it is deposited on the cam-supported carrier s of a turntable C and tipped on to one or other of the inclines of a runway D.

Abstract: 396,625. Distributers for gravel; road rollers. SCHARS, A. J., 48, Rue Achard, Bordeaux, Gironde, France. Jan. 17, 1933, No. 1543. Convention date, Jan. 25, 1932. [Class 6 (i).] Relates to machines for coating roads with asphalt, tar or the like, and gravel of the kind in which the gravel is coated before reaching the ground. According to the invention, the projection zones 25, 26 of the tar or asphalt and the gravel, respectively, partly overlap so as to provide three successively superposed layers, the first of tar alone, the second of tar and gravel, and the third or upper layer of gravel alone. In the form shown the materials are sprayed in the form of cones from rotary jets 4, 11, driven by an internal-combustion engine 8. The gravel jet 11 is mounted on a chassis and the tar jet is mounted on a frame slidable on the chassis and actuated by a screw 24 so as to vary the distance between the axes of the jets. Tar is delivered to the jet 4 by a pipe 6 leading to a tank 3, the quantity delivered being regulated by a valve 7. The gravel is stored in a vessel 10 having two compartments 10a, 10b, the latter having a sloping base leading to the jet 11. The compartment 10a also has a sloping base terminating in a trough 13 to which the gravel is supplied through a regulating door 12. The vessel 10 is initially charged by closing the door 12 and valve 18 of the jet 11 and by delivering gravel to the trough 13 whence it is conveyed by buckets 14, on an endless chain, to a horizontal endless band 16 which discharges into the compartment 10b. The band is formed with bars 16a which, when the compartment 10b is fully charged, carry the gravel to the storage compartment 10a. When the latter is filled, the valves 7, 18 and the door 12 are opened, the engine 8 is started and the vehicle is propelled along the road. The buckets 14 and band 16 are driven also by the engine 8 and together serve to keep the compartment 10b fully charged. The treated surface is consolidated by rollers 27 carried by an adjustable pivoted arm 32.

Abstract: 919,912. Ornamenting; bowling pins. VINSON, N. Oct. 9, 1961 [Jan. 17, 1961], No. 1926/61. Classes 93 and 132 (2). Sheathed or jacketed pins are produced by forming a flexible sheath or jacket 11 of polyvinyl chloride or other thermoplastic material corresponding in shape to the pin 10 but undersize in relation thereto and subsequently applying such sheath over the pin, the plastic material employed possessing sufficient resilience or stretch that while it may be applied over the pin it will when finally in place constitute a skin-tight fit thereon. The sheath or jacket may be produced on a mould or mandrel by dipping, or it may be obtained by rotational casting, vacuum forming or blow moulding. It may be formed at the lower end with a flared skirt to facilitate application of the sheath to the pin, and the skirt portion may be cut away on completing the covering operation. Preferably the sheath is expanded under pressure or in a vacuum prior to the insertion of the pin. The pin may be coated with adhesive and in this case the sheathed pin may be heated to ensure cross-linking between the adhesive and the jacket. A base cap or ring 12 of nylon or other relatively hard material may be applied to the lower end of the pin.

Patent GB-588738-A (GB)
Title: An improved electro-magnetic switch, with overload release
IPC: H01H3/02
Filed: 1945-01-25
Abstract: 588,738. Electrically tripped switches. LANDIS & GYR SOC. ANON. Jan. 25, 1945, No. 2045. Convention date, Dec. 27, 1943. [Class 38 (v)] A switch with an actuating magnet opens on overload by quick-acting release of the normally fixed contact and is re-set by a push button, which becomes inoperative as the switch closes. The switch has a moving contact 2 biassed open by a spring 10 and closed by a remote-controlled magnet 8 actuating an armature 7 and including a switch 11 in its energizing circuit. On de-energization of the magnet 8, the contact 2 moves to the "open" position. On overload a magnet 6 attracts an armature 5, releasing a lock 4, 3 and allowing a spring 1a to withdraw the normally fixed contact 1. The contact 1 strikes a lever 26 normally latching a lever 15 at 27, and levers 26, 15 rotate clockwise on spindles 25, 16, thus opening the switch 11 to de-energize the magnet 8 and causing a re-set button 12 to project through the wall 46 of the switch. The switch is switched-in again by pressing the button 12, whereby a projection 21 on a lever 19 pivoted at 17 to the lever 15 re-sets the contact 1 and thus permits the lever 26 to re-close the switch 11 and re-latch the lever 15. As the armature 7 moves to re-close contact 2, a projection 24 strikes the lever 19 out of engagement with the contact 1, rendering the switch trip-free. On excess temperature, a temperature-responsive bimetal strip 33 unlocks a latch 34, 39, releasing levers 42, 26, 15 so that the switch 11 opens and de-energizes the magnet 8. The lock 34, 39 is also re-set, in trip-free manner, by pressing the button 12. The parts 1, 2, 19 are duplicated for the second pole of a two-pole switch, a common member 18 carrying both levers 19, only one of which is provided with an arm 23. In a modification, Fig. 2 (not shown), the switch is arranged for trip-free action by coupling the button 12 to the lever 15 through an over-set toggle, which is broken by an abutment on the armature 7 when the switch closes. Specification 588,724 is referred to.
